(17) Engine oil filter housing Engine oil pump (14) has three gears that are driven by the front gear train. The engine oil pump pulls engine oil from the pan through suction bell (16) and elbow (15). The suction bell has a screen in order to strain the engine oil.Relief valve (13) controls the maximum pressure of the engine oil from the engine oil pump. If the engine oil pressure from the pump becomes excessive, the relief valve opens and some of the engine oil returns to the engine oil pan.Engine oil cooler (11) reduces the temperature of the engine oil. The engine oil cooler has bypass valve (12) that is designed to open if the cooler becomes restricted.

(10) Bypass valve
(17) Engine oil filter housing The engine oil filters are located in engine oil filter housing (17). Bypass valve (10) is located in the engine oil filter housing.The bypass valves will open if there is a restriction in the engine oil cooler or the engine oil filter. This allows the engine to be lubricated if the engine oil cooler is plugged or if the engine oil filter is dirty.Clean engine oil from the engine oil filters goes through adapter (9) into the block. Part of the engine oil goes to left camshaft oil gallery (2). The remainder of the engine oil goes to main engine oil gallery (1).Engine oil galleries (2) and (3) supply engine oil through drilled passages to the camshaft bearings. The engine oil circulates around each camshaft journal. The engine oil then flows through the cylinder head and the rocker arm housing to the rocker arm shaft. Some of the engine oil lubricates the valve stems. The remainder of the engine oil drains from the cylinder head in order to lubricate the pushrods, the valve lifters, the camshaft, and the camshaft bearings.Engine oil from main engine oil gallery (1) is supplied to the main bearings through drilled passages. Drilled holes in the crankshaft supply engine oil from the main bearings to the connecting rod bearings. Engine oil from the rear of the main engine oil gallery goes to the rear of right camshaft oil gallery (3).Sequence valves (7) and (8) allow engine oil from main engine oil gallery (1) to enter engine oil galleries (4) for piston cooling jets (5). The sequence valves will not allow engine oil into gallery (4) for the piston cooling jets until there is pressure in the main engine oil gallery. This reduces the amount of time that is required for pressure buildup when the engine is started.
